Constructional difficulty: Moderate
The power supply board in place on our 3U Master Module design. The sockets and power switch are yet to be added.
This is a dual output tracking power supply design that is perfectly suited to powering your Oakley modular. The standard design allows +/-15V at up to 800mA to be generated safely. The output is quiet and very well regulated. It is also short circuit protected. It is garanteed not to latch up on power up.
The unit is designed to be used with a centre-tapped wallwart (mains adapter) available from Yamaha. We can only endorse using this module with a low voltage input for safety reasons. However, if you have the knowledge and experience you can use this module with a internally mounted mains transformer.
It is recommended that you download and read the User Guide before purchasing this PCB.
The PCB is 140 x 81 mm. It is a double layer board with solder mask both sides and through hole plating.
The power supply board may be fitted to the recommended 3U panel or built into a self contained power supply rack case.
The power supply board inside a direct mains powered unit in a 2U 19" rack case for fitting to a rack mounted modular system. Note the Dizzy board mounted to the rear panel. This rack case also provides a 4x4 Multiple and an additional balanced audio output circuit. Neither of these is required by the power supply circuit itself.
The power supply board was originally designed to go with our Master module. This 3U wide panel includes:

A Schaeffer front panel can be made for a MOTM compatible 3U wide 'Master' module. The database for the module can be found be clicking here. To read these files you will need a copy of 'Frontplatten designer' from Schaeffer. The program also features on-line ordering, so its now even easier to buy your panels from Scheaffer.
The company are based in Berlin in Germany and will send out panels to anywhere in the world. Delivery to the UK normally takes around ten days. For North American users you can also order your Schaeffer panels from Front Panel Express.
